Vulnerability from fkie_nvd - Published: 2018-11-29 18:29 - Updated: 2026-06-17 01:44
Severity
4.2 (Medium) - CVSS:3.0/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N

Summary
Execution of Ansible playbooks on Windows platforms with PowerShell ScriptBlock logging and Module logging enabled can allow for 'become' passwords to appear in EventLogs in plaintext. A local user with administrator privileges on the machine can view these logs and discover the plaintext password. Ansible Engine 2.8 and older are believed to be vulnerable.
